Kimi-Dev-72B is an advanced open-source coding language model designed for software engineering tasks, achieving a state-of-the-art performance of 60.4% on the SWE-bench Verified benchmark. It leverages large-scale reinforcement learning to autonomously patch real repositories and ensures high-quality solutions by only rewarding successful test suite completions. Developers and researchers are encouraged to explore and contribute to its capabilities, available for download on Hugging Face and GitHub.

Tunix is a new open-source, JAX-native library designed to simplify the post-training process for large language models (LLMs). It offers a comprehensive toolkit for model alignment, including various algorithms for supervised fine-tuning, preference tuning, reinforcement learning, and knowledge distillation, all optimized for performance on TPUs. The library enhances the developer experience with a white-box design and seamless integration into the JAX ecosystem.
